Baby hairs growing again!

It might sound small, but I’m thrilled to see new baby hairs filling in a spot that’s been thin for years. I’ve been using the serum every night for about 5 weeks and my scalp feels more balanced too. It’s the first thing that’s actually made a difference for me.

Less shedding and stronger roots

After 3 months, I can honestly say this works. My hairline is filling in, and the overall texture feels denser and healthier. Even my hairdresser noticed — she couldn’t believe how much new growth I had around the temples.

Love this whole range!

I’ve been using the serum along with the MAREE Hair Repair Mask and Biotin Hair Growth supplements — and wow, what a difference. My hair feels stronger from the roots, and my stylist even said my strands look thicker. Definitely staying consistent with this routine.

Frequently Asked Questions

Apply a few drops directly to the scalp once or twice daily, focusing on areas of thinning (hairline, crown, temples). Massage in gently for 1–2 minutes to boost absorption and stimulate circulation.

No — the lightweight, water-based formula absorbs quickly without residue. It won’t weigh hair down, whether you wash, style, or leave hair as is afterward. 

Everyone’s hair growth cycle is different. Most customers notice reduced shedding and healthier-looking hair within 4–6 weeks, with visible thickness and growth in 3–4 months of consistent use.

The formula combines multi-peptides, caffeine, castor oil, and rosemary extract — ingredients studied for stimulating follicles and supporting stronger, denser growth.

Yes — it’s free from parabens, sulfates, silicones, and harsh irritants. Many customers with sensitive skin report no redness or buildup.

Despite containing rosemary and natural extracts, it has little to no fragrance — suitable for daily use, even if you’re sensitive to scents.

Absolutely. Apply to the scalp first, let it absorb, then style as usual with your regular products.

Allison Snell

MAREE Expert Advisor & IAT-Certified Trichologist

From a scalp-health perspective, the formulation is well structured. Peptides and conditioning agents help reinforce the hair at the root and reduce visible thinning. A reliable choice for improving overall hair resilience.
